Re: Pi3 WiFi stopped working

I'm guessing that you are using the sdhost overlay? Yup (or was!) That's probably not what you want on a Pi3 because it will also disable the mmc interface which is now used for SDIO. Instead, the new base DTBs have an sd_overclock parameter which does the same thing as the overclock_50 parameter o...

Re: Pi3 WiFi stopped working

Well, I have discovered what caused my problem: Increasing the sdhost overclock_50 speed on my Toshiba Exceria SDXC UHS-1 64GB card gives impressive performance gains. However it also stops the wlan0 initialisation/creation :) May be some kind of disk corruption but I am not sure. Having rebuilt the...

Re: Pi3 WiFi stopped working

my /lib/firmware/brcm directory had the same contents on both SDcards (the one that would boot with wlan0 and the 1 that had lost it). Never worked out what I did to 'break' the 1 SDcard, but am just busy rebuilding it from scratch (as it is UHS-1 64GB) and so far so good. Typing this on it via wifi...

Well still struggling, but discovered 1) It is not hardware. Using another SDcard wlan0 is there. 2) It is not the country, or at least country=GB is persistent in /etc/wpa_supplicant/wpa_supplicant.conf I suspect it is related to the "error" message when booting about wlan0: on my card which builds...

Re: [GUIDE] Raspbian Lite with LXDE GUI

Many thanks for the guide. Equally fortuitous here as my last Pi was an original in 2012 and got my Pi3 this morning so was a really handy refresher back to Debian (my normal poison is OpenSuse).

Certainly I found problems with Hynix at stock voltage, but ramping the RAM voltage, e.g.

Code: Select all

arm_freq=1000
core_freq=500
sdram_freq=500
over_voltage=6
over_voltage_sdram=4
works just peachy for me.

Looking at the code the function isn't even called so you should be able to get away with deleting it or commenting it out. You are right - commenting it out lets it compile fine and it works.

Everything is normal - presuming your laptop is running some flavour of MS Windoze.

Excellent, thanks for all this. Temp showing fine in gkrellm. Now need to write a plugin to show the clock speeds and voltages - recommend nobody holds their breathe as it is a couple of decades since my previous line of code!

If disable_overscan=1 doesn't fit the screen, it means the monitor is resizing the image, so it must be blurred. @dukla2000 See if there is an option to disable overscan on the TV.

Re: EDID with "incorrect" detail timing blocks

If the native resolution is 1920x1080 and you specify a framebuffer of 1920x1080 plus overscan, then you will have a blurry picture because the physical pixels don't align with the FB pixels anymore. Without the overscan you should get a crisp picture Makes sense to me but despite all my playing I ...

Nope, that's my entire file. I can't think of anything clever I did on my pi to get this to work after the Foundation Raspbian install. Not sure what to suggest - maybe start your script as a parameter to an xterm?
